In 1964, Eugen Monnier and Robert Zahner established a company in the industrial area Safnern-Moos, which specialized in machine tools for the manufacturing of watch cases until 1972. The watch crisis caused a shifting of the production to machines for the medical and dental industry.
In this field, Monnier + Zahner AG reached worldwide a very high standard with machines to produce medical implants, such as bone screws and bone plates as well as artificial hip joints.
Other important fields of activity include the construction of grinding machines for dental burs and machines for the production of worms and gears for suppliers to the automative industry and gear box manufacturers. This also includes customized machines, adapted to particular needs.
